500mA, 5V USB, I2C-Controlled Battery Charger with Power Path Management for Single-Cell Li-Ion Battery in QFN Package
The MP2664 is a highly integrated, single-cell, Li-ion/Li-polymer battery charger with system power path management for space-limited, portable applications. The MP2664 uses input power from either an AC adapter or a USB port to supply the system load and charge the battery independently. The charger features constant current pre-charge, constant current fast-charge (CC) and constant voltage (CV) regulation, charge termination, and charge status.
The power path management function ensures continuous power to the system by automatically selecting the input, the battery, or both to power the system. This power stage features a low dropout regulator from the input to the system and a 100mΩ switch from the battery to the system. Power path management separates the charging current from the system load, which allows for proper charge termination and keeps the battery in full-charge mode.
The MP2664 provides system short-circuit protection (SCP) by limiting the current from the input to the system and the battery to the system. This feature is especially critical for preventing the Li-ion battery from being damaged by excessively high currents. An on-chip battery under-voltage lockout (UVLO) cuts off the path between the battery and the system if the battery voltage drops below the programmable battery UVLO threshold, which prevents the Li-ion battery from being over-discharged. An integrated I2C control interface allows the MP2664 to program the charging parameters, such as input current limit, input voltage regulation limit, charging current, battery regulation voltage, safety timer, and battery UVLO.
The MP2664 is available in a QFN-10 (2mmx2mm) package.
Evaluation Board for 500mA Linear Charger with Power Path Management for Single-Cell Li-Ion Battery in a QFN Package
The EV2664-G-00A is an evaluation board for the MP2664, a highly integrated, single-cell Li-ion/Li-polymer battery charger with system power path management, designed for space-limited portable applications. It takes input power from either an AC adapter or a USB port to supply the system load and charge the battery independently. The charger section features constant-current pre-charge (PRE.C), constant-current fast charge (CC) and constant voltage (CV) regulation, charge termination, and charge status.
The EV2664 ensures that there is continuous power to the system by automatically selecting the input, the battery, or both to power the system. It provides system short circuit protection to prevent the Li-Ion battery from being damaged due to excessive high current. The EV2664 cuts off the path between the battery and system when battery UVLO is reached to prevent the Li-Ion battery from being overly discharged.
Through the I2C connector on the EV2664, the user can program the charging parameters, such as the input current limit, input minimum voltage regulation, charging current, battery regulation voltage, and battery UVLO.
